Air suspension help please!!!!!!!!!!

[Delaneycatz]

Hi all

i am have the dreaded air suspension issue. I have replaced the pump and solinoid but no success. At the moment when I start my 2005 cayenne all is fine and the pump runs but when it cuts off after about 20 seconds the air suspension light comes on. Any pointers please as I suspect this isn't a normal issue. I have read that the battery if it's not at 100% can throw things out but not sure. Has anyone else suffered with this issue and found a fix. Info greatly appreciated.

thanks in advance

Did you replace the entire pump, or just the o-ring? I did the latter once with an EBay kit and the o-ring fit was poor. I replaced the o-ring with one from bagpipingandy and it fixed it. The computer looks to see if there’s a tank pressure increase on startup. If not enough, then you get the error. It’s likely the pump or the line to the tank, and most likely where it comes out of the pump. Try spraying the pump and lines with soapy water and then doing the start routine. Check for bubble indicating a leak. Careful, don’t accidentally run over yourself. Good luck.

Hi. I have tried both. My pump seems ok. Fault code suggested the solinoid so obtained a replacement albeit from a breakers. This came with a pump so changed at the same time. I did however while it was out change the ring. Thanks for your suggestion. Will strip the cover again today and explore air leak. Could my issues be caused by faulty Ecu or relay?

thanks for your advice
